German's official cyber-security response team is advising surfers not to use Firefox pending the release of a patch to defend against a critical unpatched vulnerability.

BürgerCERT, a division of the German federal government's security in information technology (BSI) department, warned surfers to steer clear of the open source browser until Mozilla releases a fix, due on 30 March.
